The Author RSS Widget is very similar to the default RSS widget but offers author-specific RSS feeds. This means that you can display the RSS feed of your authors on their author archive page or posts that they’ve written.
<h4>Usage</h4>
The plugin gives you 5 options to tweak. The “Title” and Items To Show” options should be pretty self-explanatory. The former controls the widget’s title, the later controls the number of items displayed from the feed.
The “Field Name” option is needed because there is no built-in way to add an author’s feed URL to WordPress. Author RSS Feed needs to know how you saved this data to the database. Add user meta field name you are using here.
There are a number of ways to add additional fields to the user edit screen, I recommend <a href="https://wordpress.org/plugins/advanced-custom-fields/" rel="ugc">Advanced Custom Fields</a>. Once you’ve added a field to the User Form make sure to use the generated “Field Name” here in Author RSS Field.
The “Default Field URL” setting can be used as a fallback. If an author’s feed can not be found or the widget is displayed on any other page than the author archive or single post page, this URL will be used. It may be left empty, in which case the widget will not be displayed at all. This is useful if you either want to show the author’s RSS feed, or nothing at all.
The “Show Feed On” setting controls when the author’s RSS field overwrites the default RSS field. This allows you to show the author’s feed on his/her author archive, but not on single post pages.

How it works
Go to your widgets section. Drag and Drop the widget in a sidebar(widget area) that you want your list to appear in. Fill in the form and click save. Here are the options you can choose from:
<ul>
<li>Select multiple categories and tags to list posts from.</li>
<li>Choose the number of posts to list and where to start listing from.</li>
<li>Order the list by: author, date created, date modified, post title.</li>
<li>Order to display posts: ascending, descending.</li>
<li>Select fields you want to show: title, date, excerpt, number of comments.</li>
<li>Select excerpt length in words</li>
<li>Choose to show image on: all posts, first only or none</li>
<li>Choose size of the image: thumb, medium, large</li>
<li>Choose image float: top of text, left of text, right of text</li>
</ul>
By filling a simple form this plugin will build an SQL SELECT query, return a result set and build html code based on it. The form controls select expression, where condition, order by expression, limit expression. 
No coding is required!
